FS - Pavel Dudek PA-03, Sjostrom QRV-08

I've got some projects needed to sell to make room for new ones. Most of them are pretty much new, with very low hour usage.

Except the DAC, all the other are 220v mains only.
Shipping will be from Vietnam by Registered Airmail with tracking number.

Would consider any audio parts in trade.

1. Quanghao DAC-END 24 with Amanero USB and 6dj8 output stage.

Excellent sounding DAC which could rival other multi-thousand units. Very carefully chosen parts.
Wooden faceplate and custom made casing. Every feature works perfectly.

More info could be provided if interested.

Could be switched to 110v mains votage.

SOLD


2. Pavel Dudek PA-03 amplifier.

Easily my most favorite chipamp, no question about that.
Top-of-the-line parts were chosen, machined solid block of aluminum used as heatsink, PRP resistors, Nichicon KA Audio caps,
Cornell-Dubilier power caps, LME49720NA opamps, custom made 300VA toroidal transformer,
Schurter filtered inlet, CMC silver RCA and speaker connectors (a bit oxidation though), full aluminum case.

220v mains ONLY. Could sell without the transformer if really interested.

Asking price $675 + shipping + PP fee.
Just the amp board, no case, no transformer: $475 + shipping + PP fee

3. Sjostrom QRV-08 headphone amp.

By far the best headphone amp by Sjostrom Audio: Sjöström Audio - QRV08 Headphone amp

Hand soldered with thin metal film resistors. ALPS Rk27 volume pot. A piece of art, just by the look.

Could also use as a stunning preamp.

Interesting features:


  • High speed, low distortion current feedback design.
  • All discrete design of the amp itself.
  • Offset trim with a trimpot and/or with a DC servo.
  • Input LP-filter if you have problems with RF interference (you should have a filter though).
  • Room for DC removal cap (if you need this)
  • High speed and high performance SMD buffer as output stage.
  • High current transistors as output stage.
  • Extremely high quality dual mono power supply with large smoothing caps and transformers on the pcb and with four extremely high speed and high performing super regulators.

220v mains ONLY.

Asking price $325 + FREE shipping + PP fee.

Regarding the PA-03, I could sell the working board only, without the transformer and case, if anyone interested. That way would save significant cost and you could use your desired mains voltage, instead of only sticking with 230v. I could throw in an Alps RK27 for free if you want to add a volume control. Price added in the first post.

Taking reasonable offers too.
